    Je les adore!

    J’ai un lichen scléreux vraiment mal contrôlé (problème de peau) et ces sous-vêtements m’aident beaucoup en absorbant l’humidité. Ça fait des années que j’ai des problèmes et j’ai vu une amélioration dès les premiers jours.

    Comfortable!

    These work for me. No chafing around the legs and the material is nice. I wash them separately although they claim it’s not necessary. I always hang inside out to dry.

    No more “diapers” for bed!

    I bought these specifically for overnight protection. I use a period cup but on my heavy nights, I’d wear a massive overnight pad for leakage and I hated it! So often it seemed the pad was never giving coverage where I needed it and it would leak. Plus I felt like I was wearing a diaper! These underwear feel like you’re not wearing anything and for the first time, I wasn’t worried that I’d have leaked beside the pad. These had me covered!

    Comfortable!

    These are so comfortable! I upgraded from older Knix and these are so much slimmer, but just as absorbent.

    Perfect

    These are everything I've looked for. Front to back coverage, plenty of leg room, generous fit without being loose.
